Ms. Yamada runs the school cafeteria. In October, she had to order 15 cases of chocolate milk twice because the students at her school love it so much. Each case contains c cartons of chocolate milk. Pick all the expressions that represent how many cartons of chocolate milk Ms. Yamada ordered in October. Multi-select Choices: (A)2c + 15c (B)2(15c) (C)30c (D)c(2 + 15)

Calculate cases ordered: Calculate the total number of cases ordered in October. Ms. Yamada ordered 15 cases twice, so: 15 cases * 2 = 30 casesDetermine total cartons: Determine the total number of cartons ordered. Each case contains c cartons, so for 30 cases: 30 cases * c cartons/case = 30c cartonsMatch total cartons expression: Match the expression that represents the total number of cartons. From the choices given: (A) 2c + 15c = 17c (Incorrect, doesn't match 30c) (B) 2(15c) = 30c (Correct, matches the calculation) (C) 30c (Correct, directly matches the calculation) (D) c(2 + 15) = 17c (Incorrect, doesn't match 30c)

Pick all the expressions that represent how many cartons of chocolate milk Ms. Yamada ordered in October.

\newline

Multi-select Choices:

\newline

(A)

2c + 15c

\newline

(B)

2(15c)

\newline

(C)

30c

\newline

(D)

c(2 + 15)

Calculate cases ordered: Calculate the total number of cases ordered in October. $\newline$ Ms. Yamada ordered $15$ cases twice, so: $\newline$ $15$ cases $\times 2 = 30$ cases
Determine total cartons: Determine the total number of cartons ordered. Each case contains $c$ cartons, so for $30$ cases: $30$ cases $\times c$ cartons/case $= 30c$ cartons
Match total cartons expression: Match the expression that represents the total number of cartons. $\newline$ From the choices given: $\newline$ (A) $2c + 15c = 17c$ (Incorrect, doesn't match $30c$ ) $\newline$ (B) $2(15c) = 30c$ (Correct, matches the calculation) $\newline$ (C) $30c$ (Correct, directly matches the calculation) $\newline$ (D) $c(2 + 15) = 17c$ (Incorrect, doesn't match $30c$ )
